I thought those taillights slightly were reminiscent of a Plymouth Cricket...I really thought it was a non-US variation but couldnt find a match online. This one was bugging me. I believe this was indeed related to the cricket in some way.

Cortinas were assembled in New Zealand from '62 to '82 from Dagenham CKD kits. When the Dagenham supply ran dry in mid '82 a final batch of CKD kits were supplied by Fords Irish factory in Cork and the last New Zealand Cortina was assembled in mid'83.
